Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488728, here are decompositions:

37 + 2147488691 = 2147488728
109 + 2147488619 = 2147488728
149 + 2147488579 = 2147488728
211 + 2147488517 = 2147488728
311 + 2147488417 = 2147488728
317 + 2147488411 = 2147488728
347 + 2147488381 = 2147488728
421 + 2147488307 = 2147488728

Showing the first eight; more decompositions exist.
